Collapse of Foundation Wall (August 2011)

Photos below show effects due to total collapse of long segment of block foundation wall supporting commercial building in Pennington NJ. Height of soil backfill against the wall had already exceeded standard limits such that the wall was already cracked. Water from tropical storm Irene saturated backfill, providing additional pressure that resulted in total collapse into basement.

Remaining walls around basement were also cracked and pushed inward, due to excessive height of soil backfill pushing against these walls.

Photos below, showing construction of a segmental concrete bridge in New Jersey, are for general interest. Design was performed by others for NJDOT. The bridge is now completed and open for traffic in both directions.
